The majority of the CIS research activity focuses on carrying out public opinion surveys. These surveys include electoral studies, its monthly public opinion barometers, monographic studies on different aspects of Spanish society and the surveys resulting from CIS involvement in international projects.
All the surveys the CIS takes are deposited in its Data Bank, and they are available to the public once the quality control, verification, anonymisation, codification and information uploading tasks have been concluded.
In addition to its surveys, the CIS also collects information about Spanish society through qualitative research studies: Fundamentally, discussion groups and in-depth interviews.

The German Socio-Economic Panel Study (SOEP) is a wide-ranging representative longitudinal study of private households, located at the German Institute for Economic Research, DIW Berlin.

Some of the many topics include household composition, occupational biographies, employment, earnings, health and satisfaction indicators.

MTSA is a Metropolitan Travel Survey Archive to store, preserve, and make publicly available, via the internet, travel surveys conducted by metropolitan areas, states and localities. As a result of cooperation from several agencies, we now have been able to post databases along with relevant documentation for many regions in the archive http://www.surveyarchive.org/archive.html . The databases and the documentation can be obtained from this website. In addition to making these databases publicly available, we are also in the process of converting all the databases to a common format to enhance the readability and usability of each survey, so many surveys can be used online, see analyze http://www.surveyarchive.org/analyze.html. The results from the first year of the project, along with issues related to archiving travel survey data are provided in our reports page http://www.surveyarchive.org/reports.html . Papers written by Yacov Zahavi, an instrumental figure in the development of travel surveys, are also provided here.

It is the executive office of the UK Statistics Authority and although they are separate, they are still closely related.

TRAILS is a prospective cohort study, which started in 2001 with population cohort and 2004 with a clinical cohort (CC). Since then, a group of 2500 young people from the Northern part of the Netherlands has been closely monitored in order to chart and explain their mental, physical, and social development. These TRAILS participants have been measured every two to three years, by means of questionnaires, interviews, and all kinds of tests. By now, we have collected information that spans the total period from preadolescence up until young adulthood. One of the main goals of TRAILS is to contribute to the knowledge of the development of emotional and behavioral problems and the (social) functioning of preadolescents into adulthood, their determinants, and underlying mechanisms.

The Fragile Families & Child Wellbeing Study is following a cohort of nearly 5,000 children born in large U.S. cities between 1998 and 2000 (roughly three-quarters of whom were born to unmarried parents). We refer to unmarried parents and their children as “fragile families” to underscore that they are families and that they are at greater risk of breaking up and living in poverty than more traditional families.
The core Study was originally designed to primarily address four questions of great interest to researchers and policy makers: (1) What are the conditions and capabilities of unmarried parents, especially fathers?; (2) What is the nature of the relationships between unmarried parents?; (3) How do children born into these families fare?; and (4) How do policies and environmental conditions affect families and children?
